Scratching that new allowance itch, Systrom and Krieger partied in Las Vegas, first dining at Botero at the Wynn with Jesse Waits (left bottom), the club managing partner at Encore’s XS nightclub, and DJs Deadmau5 (top left) and Avicii (bottom right). They then traveled to XS. Reportedly they ordered a bottle of Armand de Brignac "Midas," the world's biggest bottle of champagne. Cost? $150,000.
